Question
In an experiment the equilibrium between ethanol, acetic acid, ethyl acetate, and water is studied, and the reaction is catalyzed by the addition of hydrochloric acid.
Following mixtures were prepared and titrated with 0.953M NaOH solution to calculate equilibrium constant of the reaction.
Mixture 1. 2.5ml 3M HCl+ 2.5ml Water
Mixture 2. 2.5mL 3M HCl + 2ml Ethyl Acetate + 0.5ml Acetic Acid
End points were reached at 6.68 ml and 24.36 ml, respectively. Calculate the equilibrium constant using mole fractions for the reaction (MWHCl: 36.46g/mol, MWCH3COOH: 60.05g/mol, MWH2O: 18.02g/mol, MWCH3COOC2H5: 88.11g/mol, ρwater = ρHCl =0.998g/ml, ρCH3COOH = 1.05g/ml, ρCH3COC2H5 =0.902g/ml)
